Math Problem

Dear Friends:
Trying to break the builders block got new ink printed the 1929 Bugatti #12 at 92% to fit paper if the model is 1/30 scale did I just manage to print it to 1/32 scale and will be able to go into old hobby stuff and find a 54mm figure in lead to do a diorama. Math I did 30/.92=32.---- is this right???
Thanks,
Miles
Begin to think that I should take it to copy shop and blow it up to 11x17 for ease of building.

The usual trick is:

"Scale you've got divided by the scale you want and then multiply the answer by 100 to get % to print it out at."

(I don't remember who I am quoting, I know is some one from this forum, but forgot to copy the name. I just copied the trick to a txt file. Sorry)

By that math, to go from 1/30 to 1/32 the kit must be printed at 93.75

a 1.75% difference doesn't look like much. Maybe just a couple of millimeters.



Edit:
I found the thread discussing scale conversion.
Scales and resizing.

Above I was quoting Piginapoke. Is the last comment in that thread.

Or multiply the first answer by any value or dimension you've got to get the equivalent rescaled value or dimension.

I wouldn't stress if there is a small difference!

If you want to display it with something, just more the something else back or forward depending on it's scale for perspective.

E.G. If if you have a 1/72 model and a 1/76, you place the 1/72 towards the front....

Dear Friends:
thanks guys nice to know that I was doing the math right. Now look for brick road service in 1/32 scale for a base. In 1929 what was the road surface at Le Mans? Still on Step One will start to take photos for a build report.
Thanks
Miles

Miles, in 1929 there was a left hand turn only that was bricked (known as the Indianapolis Turn!), the rest of the track being "local road" surfaces. Some were possibly asphalt.

Maybe look at some photos from the period?

Tracks were dirt up to the mid twenties - there were regulations restricting down pointing exhaust pipes because they blew up too much dust.

I usually take the following approach.

1/30 to 1/32 ... If you wish to make the scale smaller, you would have a calculated value less than one. You take the denominators and place one over the other. The scale you want to go to as the denominator and the scale you want to go from as the numerator.

Scale From
Scale To

ex. 1/30 to 1/32 is represented as 30/32 or 0.9375 which is 93.75%

An aircraft papermodel with a scale of 1/33 which you want to print off and assemble to be scaled with a tank 1/25.

ex. 1/33 to 1/25 is represented as 33/25 or 1.32 which is 132.00%

what about a 1/400 model at 125% what would be the new scale? 400 / x = 125? so to get x by itself divide both sides by 400 so we have x = 125 / 400, x = .3125 or 1/312 scale? is this the right math?

400/x = 125
multiply both sides by x to get rid of the denominator
400 = 125x
divide both sides by 125 to solve for x
400/125 = 3.2 or 1/320 scale.

Solve 400/x=125 Tiger Algebra Solver
